How it all started

When Philipp and Marketa were first confronted with the challenge of raising two children in a digital world, the lack of thoughtful solutions was overwhelming.

Philipp Hartmann

Philipp Hartmann

Co-Founder

Limitless content, dangerous algorithms, and no safety controls created stress when there should’ve been excitement, fear instead of joy. Determined to change the status quo, we started prototyping some ideas which quickly evolved from a small side project into a rapidly growing company, dedicated to making a lasting impact on the way young children experience technology.
